They are the same thing and made by the same people. I have the purple Vidal Sassoon set and the Caruso set. The Vidal Sasson set was $13.99 at Ross, My Caruso $25 at Sally's. Both have the identical set of instructions, warranty information and the same rollers, only in different colors. The only difference is the color of the rollers and my Vidal Sasson also has an ionic setting.
